What can you process with a screening bucket?

Preparation of topsoil, composting, and recycling are the most common applications of screening buckets. The screened fraction obtained can be classified as a clean, high-quality soil free of oversize stone, etc. Buckets can also be used to mix sand, clay and compost to achieve the desired consistency required for a specific use.

  • Remu aeriating and mixing compost

    Aerating and Mixing Compost

    Mixing and aerating organic waste piles will speed up the composting process. More aggressive blades, such as screening-crushing blades, break the material into smaller particles to catalyze the process. Composition can vary from very moist to dry, depending on the type of material and how advanced the composting process is. In the early stages of the process, a bucket with very large gaps between the blades can be used to mince up particles and aerate the material whilst later in the process the compost can be screened using a bucket with narrow blade spacing between the screening blades to separate any remaining oversized particles from the end product. The screening buckets are compact and are easy to bring inside any composting installations.

    Material: Dried and composted sewage sludge
    Objective: Remove remaining oversized particles from composted material
    Bucket model: EP 4150

    The operating principle of shaft screens

    REMU screening buckets have between 2 and 4 rotators powered by hydraulic motors. The spinning motion of the rotators and the carefully designed shape of the blades create movement that effectively separates the fine material, which drops through the bucket, and oversized particles, which remain inside the bucket. Because of this up and down movement, even material that is moist and thus hard to process with vibrating or sifters screens, is easy to process with the REMU blade screens.

    Blade designs

    Our blade designs can be divided into three groups: 1) Screening blades genuinely the materials without breaking up large particles thus avoiding them passing into the screened product. 2) Aggressive blades are designed to mince and break up materials like glass, roof tiles, root lumps. 3) Block shafts are designed to mix or aerate material, and are also used for coarse screening.

        Cleaning scrapers

        Blade screen technology is the best choice for moist materials. Rotating blades make the material move up and down while cleaning scrapers, constantly cleaning sticky material off the shafts.

          Q&A on our Screening Buckets

          How much material you can load into the bucket?

          REMU screening bucket can be loaded fully which gives you more capacity at each scoop whilst trommel style buckets can be only filled to 1/3 of the bucket volume.

          What is the production per hour?

          To process one bucket load takes approximately one minute. This includes whole cycle of processing starting with loading, screening, and emptying out the oversized particles. Depending on the bucket size capacities can be in the range of 10 m³/h – 250 m³/h per hour.

          What is the operational cost of the screening bucket?

          One operator, one machine and a screening bucket is an unbeatable combination when compared to what it takes to run a screening plant. By investing in a screening bucket, you save on investment cost, operating costs as well as fuel, maintenance and equipment transportation costs.

          Some other buckets are cheaper than REMU buckets, why is that?

          A reliable and robust structure keeps your machine up and running saving you time and money in both operation and maintenance. Shafts are made of highest quality steel which gives you the longest possible service life (much longer than other buckets with rubber stars or blades with that are made from lower quality steels).

          Why are there so many models of the REMU screening bucket?

          A wide selection of models and our professional sales team helps to guarantee that you will get the most suitable model and configuration of screening bucket and shafts for your machine, the material you process and the end-result you require.

          Can I use a bucket on asphalted surfaces?

          The design of the buckets takes in consideration that clients may be working on asphalted surfaces and the bottoms of our buckets are reinforced with wear plates.

          Is it difficult to operate screening bucket?

          It is very easy to learn how to operate a screening bucket. We supply a user manual with instructions for the correct use of the bucket and we will be happy to clear up any doubts you may have.

          Why choose a screening bucket over a screening plant?

          When comparing larger screening plants to smaller or average size screening buckets, some screening plants process more material per hour than screening buckets. However, a screening plant needs a wheel loader or an excavator to feed it, so you are running two machines and may need a second operator. In many cases, the hourly production of the right model of screening bucket is the same as a screening plant, but the size of the initial investment and the operating costs are just a fraction of the size. With a screening bucket, productions of 250 m3 per hour are possible.

          What maintenance does a screening bucket require?

          Basic maintenance, or even changing the rotors, is easy to perform in any workshop. Daily maintenance consists of greasing the lubrication points for the bearings. Our aftersales service provides detailed instructions for all the maintenance.
